“Laze” Hazard at Kīlauea Lava Ocean EntryMay 21, 2018, 7:29 AM HST · Updated May 21, 7:33 AM 3 Comments
The Coast Guard is enforcing a Lava Entry Safety Zone for waters surrounding the the new lava entry into the Pacific Ocean at Mackenzie State Park in Lower Puna. The safety zones includes navigable waters extending 984 feet in all directions around the lava ocean entry.
Authorities warn that getting too close can result in serious injury or death. Officials with the Hawai’i Civil Defense agency say lava entering the ocean produces laze, which is formed when hot lava hits the ocean sending hydrochloric acid and steam with fine glass particles into the air.
In addition, ground deformation, seismic activity, newly formed lava delta or existing cliff collapses are all coastal hazards, including the potential for localized tsunamis along the coastline and out to sea.
Enforcement of the Lower Puna safety zone began on Sunday morning.
Lt. Cmdr. John Bannon, Coast Guard Sector Honolulu waterways management lead said, “All waterway users should be aware of the hazardous conditions associated with such an event. Getting too close to the lava can result in serious injury or death.”
Based on a review of nearly 30 years of lava and ejection distance observations in the Hawaiʻi Volcano Observatory records, a radius of 300 meters was determined as a reasonable minimum high hazard zone around a point of ocean entry.
Another Explosive Eruption at Kīlauea Summit
Meantime, another explosive eruption was reported at the Kīlauea summit on Hawaiʻi Island overnight. The incident was reported at around 12:55 a.m. on Monday, May 21, 2018.
The Hawaiian Volcano Observatory reports that the resulting 7,000 foot ash plume may affect the surrounding areas with wind carrying ash to the southwest toward Wood Valley, Pāhala, Nāʻālehu and Waiʻōhinu.
Scientists also continue to monitor the two active lava flows that have entered the ocean off Highway 137 near MacKenzie State Park.
Since the eruption onset in the East Rift Zone on May 3, 2018, a total of 47 structures have been destroyed.
